the diff is in the bandwidth capability.. if you are not maxing it out.. then should not have any issues

eh? how come digital cables like HDMI, wah! got people experience improved color brighter, sharper etc? all analog "audiophile type" symptoms biggrin.gif

for HDMI cables under 3-5Meters most of all cheapo and expensive ones produced same pass results for 1080p at 12bit color i.e. to pass digital "Eye pattern" tests using tektronix digital analyzer...

from the earlier posted article below.
http://www.audioholics.com/education/cable...tion-conclusion

digital artifacts are as such = (described for a super long 65ft HDMI double jointed cable)
"What was occurring was real-time video, but with frequent, rapid-fire areas of snow on the picture which made the movie pretty much unwatchable. Periodically, the entire picture would turn to snow or flicker off for a moment before it came back and attempted to render itself to the best of the double cable's potential."

so conclusion is if u need longer HDMI cable like 10m,it's better to choose GOOD HDMI then normal non-brand HDMI cable? The thing is a GOOD hdmi count on length so 10m easily cost u arround RM800-RM1000,so mind to share what's the 10m hdmi cable u guys using now ?
*
yes that's a good conclusion based on length required..
and if the HDMI cable does show problems, they show DIGITAL artifacts like "image snow" or Purple video, video flashing white frames etc.

HDMI DIGITAL cables doesn't give you improved color, improved visual definition, improved Y/C definition etc. those are S-video/component/composite analog cable attributes. I'm gonna laugh to death if another HDMI cable seller start claiming these beneifits for their digital cables.. biggrin.gif biggrin.gif

ok,just to confirm,the conclusion is even HDMI cable at longer length,say 10m or more,as long as it doesnt show problem like  image snow or purple video, video flashing, white frames etc,the cable consider PERFECT ? If yes,that means even u change to better quality cable which cost 5-10 times more,it wont improve the PQ,not even in brightness,contrast..... ?  hmm.gif

if the cheapo 10meter cable that you have, doesn't show any problems listed then it's fine to use it.. you won't get better results using something that costs 10x more.. LOL... it's not a video processor to "Add/subtract" or "improve/degrade" any analog video elements into the digital signal..


"If yes,that means even u change to better quality cable which cost 5-10 times more,it wont improve the PQ,not even in brightness,contrast..... ?"

by asking this question, means you don't understand the difference between digital and analog.
no point to go further until we understand what is digital and analog signal concept.. smile.gif cheers!

however HDMI does have different specifications and i think what in the HDMI market now is either 1.3 or NONE 1.3

from http://en.wikipedia.org/wiki/High-Definiti...media_Interface
it does mention something about Deep Color for 1.3

therefore for people who claim they see the difference between cheap and expensive HDMI cable maybe is due to one of the following:
1) it is true, PQ is different (i dont own expensive cable so i cant say anything)
2) one is 1.3 version cable and the other is not
3) using different HDMI ports to test (each port has its own PQ settings)
4) using different equipments to test
*
1. no need to have expensive cables to know there is no difference. it's digital. biggrin.gif
it's like your digital USB2.0 cable or SATA..
you have a file say 10MB size which you copied from hard disk A to harddisk B , suddenly you notice the file size of the file has grown 5% to 10.5MB after the transfer .. or suddenly your Word document which contains 1000words suddenly have extra 10words after transfering to another HDD biggrin.gif

this is what these people are saying in relation to improved video quality and different priced HDMI 1.3 cables.... as though the digital signal can "improve" or "degrade" the analog video source, in the traditional manner (i..e improved/degrade analog attributes like contrast, Y/C , etc) used to compare analog video cables.

ever heard the saying: fools and their money soon depart. Hahaha.
Anyway for normal length 2-3mtr branded hdmi cable between the same brand low end and high end also cant see difference how to justify the diff in price? If want better visuals better spend more on the screen. I..e. tv/proj.

ar188 quoting good example, the different between USB 2.0 vs e-SATA is the transfer speed, but the "digital" content, a.k.a. "file" is the same after transferring.  rclxms.gif

and just to add, if there is indeed some error on the files or data being transfered, it will be corupted digitally..
as for corrupted HDMI video signal, won't suddenly be less sharp or slightly blur or lower contrast/brightness.. biggrin.gif it'll will be very drastic like flashing white frames, sparklies, purple image, snowing etc.. you will know it's something wrong when you see it. biggrin.gif

thickness does it meant hav additional sheilding? does it necessary for hdmi? i tot its only useful for power cables

regarding bmw, unless d bmw is fully paid then they deserve d notworthy.gif, if still under hp... remember to pay on time, later kena finance tow back d bmw laugh.gif

yeah sometimes the thickness has to do with the external sheath and shielding, and not the wire cores it self..

as for the BMW... it's between the finance company and the owner whether they pay or not pay or kena tow..
anyone talking like this, sounds like having a big case of inferiority complex... sorry, just my 2 cents.. biggrin.gif

Question guys...

When I watch Spiderman 3 BD,

There's noise at black part...

why aaa ?...

i watch with ps3, HD ready, 100hz 32"...

Does the problem come with cheap HDMI ?...

I dont have any other BD to test );
*
I did discuss with with mpyw (another big time bluray fan and previously Sony TV supporter) tongue.gif
this movie and a few other BD got lots of "digital grain or specks" showing thro their sony 1080p TVs at the sony store demos, I also dunno why.. maybe the sharpness is dialed maximum??
I really donno this weird phenomena..

yeah it pretty bad, but I don't think it's the HDMI cable.. maybe the settings in the TV.. but strange the sony shop people can't notice these artifacts wan.. what;'s the use of selling 20k Full HD TVs.. tongue.gif

it's very simple, to proof it one and for all, just take photo of the image of of the TV screen.. like they do when comparing projector A and projector B image quality.

cos for video quality , no need the "golden eyes" to see the diff, photo shots with the same room conditions and camera settings and pause at certain scenes can already proof if there is difference or not.
(unlike those mythical golden ears elites when comparing Subwoofer/amp/speaker/CD player)

so far I still haven't come across any professional website/magazine who review the HDMI cables this way (they seem to only review it with the digital signal analyzer for signal integrity)

which is surprising cos they do so this way (image capture) with different projectors to analyze the whole image quality down until sub pixel level quality (like those out of aligment subpixels and even screen door effect)..
so why is that?

I just got a China brand HDMI 1.3b cable for my NMT. Comparing with the free HDMI cable came along with my pioneer dvd player, the picture is now slightly brighter then before.  tongue.gif

if china HDMI1.3b vs Monster cable, I wonder if it's even more "clear" biggrin.gif

ok,below are 2 screenshot taken using 2 different HDMI cables,one "MP Acoustic( RM35 )" and the other " Panasonic RP-CDHG15 ( RM170,maybe kena potong:P)".Both picture taken with same camera/setting/time/place/scene,original pic without processing,reduce size in CS3 for posting.

1)
user posted image

2)
user posted image

i'm sure there're some kind of compression and lost in quality during the process of "reduce size,web hosting" but both using excactly same methob for above action,no a proper serious comparison,just corious to know the result,guess which one by which cable? Or no different at all?  tongue.gif

looks like exposure levels/lighting conditions from camera's each shot are different... (did you use the SOP** i.e. "graycard" and manual white balance, shot in RAW)

could say that the top one is more white balanced (bottom photo, lefthand blue screen side looks white washed)..
but then again the the bottom one can see more details near the right side, on the darker feathers.. so how?

maybe a rm1k HDMI cable would have best from both images? tongue.gif




"The single WhiBal card is light Gray, certified to recommended Luminance level of L* = ~75, which is optimum for use in all RAW converters.

Having a "GrayCard" reference is the best assurance that the digital pictures that you capture will have the ability to be properly White Balanced. Only with a proper White Balance can you be ensured of proper and accurate color, regardless of lighting conditions. Unlike your eyes, a digital camera does not automatically see whites as white. It sees the color of the light reflected from it, hence blue-ish in Daylight and Orange-ish in incandescent lighting. By photographing a Gray Card reference for each lighting situation that you are in, you are assured of being able to achieve a proper White Balance for all of your pictures.The Gray Card reference picture can be used with today's software to balance the color casts that various lighting conditions produce with all digital cameras. The best method to properly White Balance your digital pictures is by using a Gray Card properly and shooting RAW. RAW Conversion Software such as Adobe Camera Raw and RawShooter can then perfectly adjust all the captures that were shot under the same lighting conditions."

definitely.. as I have mentioned few pages back.. people obsessing too much with the digital cables rather than the screen it self..
